Can anyone tell me where this analysis went wrong

I tried linear static analysis of plate with hole and applied boundary conditions in 2 different methods i.e., applying force (1000N) on independent load and applying force (21.3N) on all the centred nodes (so total 1000N)

 

But analysis results and stressed regions are totally different

Can anyone tell me why?

I attached images for reference

    Sreekanth,

    What type of 1D element (ie spider) are you using to distribute the force load? It should be a RBE3 (ie flexible) type of 1D element.

    It Solved the problem by changing from RBE2 to RBE3???????? Thank you Joshua Pennington
